Purpose: To validate the International Classification of Diseases, 10th Revision (ICD-10) codes for Guillain-Barré syndrome (GBS) in Taiwan's insurance claims database.

Methods: We identified adult patients hospitalized at any Chang Gung Memorial Foundation branch hospital between January 1st, 2017, and December 31st, 2022, with ICD-10 code G61.0 in any of the five discharge diagnosis positions, indicating possible Guillain-Barré syndrome.

Article Synopsis
  • The study highlights an increasing prevalence of ischemic strokes in young adults, particularly linked to Fabry disease, which is often undiagnosed.
  • A cohort of young adults aged 20-55 who had recent ischemic strokes was screened for Fabry disease using blood tests, leading to genetic testing for those with positive results.
  • Out of 977 patients, two were genetically confirmed to have Fabry disease, suggesting a low prevalence in this group, which could inform future screening policies.

Introduction: Developing an effective stroke prevention strategy is crucial for elderly atrial fibrillation (AF) patients with dementia. This is due to the limited and inconsistent evidence available on this topic. In this nationwide, population-based cohort study, we aim to compare the effectiveness and safety of direct oral anticoagulants (DOACs) and warfarin in AF patients with dementia.

  • * Data from 670 patients revealed that while IVT may improve some outcomes, such as higher chances of achieving a modified Rankin Scale score of 0-2 in univariable analysis, this benefit was not consistently observed in more rigorous multivariable analyses.
  • * Overall, the findings suggest that adjunctive IVT may not significantly enhance clinical outcomes or safety compared to MT alone for this patient population.

  • Mechanical thrombectomy is the standard treatment for large vessel occlusions, but there's limited evidence for its effectiveness in treating distal and medium vessel occlusions, particularly for patients with low stroke scale scores (≤6).
  • A study analyzed data from 41 academic centers, comparing outcomes of low versus higher stroke scale score patients who underwent thrombectomy, revealing high successful reperfusion rates in both groups.
  • Results showed that patients with lower stroke scale scores experienced better functional outcomes and lower mortality rates, but the treatment's effectiveness compared to intravenous thrombolysis (IVT) is still uncertain.

Background: Optimal anesthetic strategy for the endovascular treatment of stroke is still under debate. Despite scarce data concerning anesthetic management for medium and distal vessel occlusions (MeVOs) some centers empirically support a general anesthesia (GA) strategy in these patients.

Methods: We conducted an international retrospective study of MeVO cases.

Background: Mechanical thrombectomy (MT) has revolutionized the treatment of acute ischemic stroke (AIS) due to large vessel occlusion (LVO), but its efficacy and safety in medium vessel occlusion (MeVO) remain less explored. This multicenter, retrospective study aims to investigate the incidence and clinical outcomes of vessel perforations (confirmed by extravasation during an angiographic series) during MT for AIS caused by MeVO.

Methods: Data were collected from 37 academic centers across North America, Asia, and Europe between September 2017 and July 2021.

  • The study aimed to evaluate the effectiveness and safety of the pRESET LITE stent retriever for treating medium vessel occlusions in acute ischemic stroke patients.
  • A retrospective analysis included 227 patients from 37 institutions, distinguishing between proximal and distal occlusions, revealing successful reperfusion rates of 85% and 97%, respectively.
  • Despite a 7% complication rate and a significant percentage of patients experiencing hemorrhagic transformations, the procedure showed a favorable outcome in 58% of cases after three months.

During the COVID-19 (coronavirus disease 2019) outbreak, many people were infected, and the symptoms may persist for several weeks or months for recovering patients. This is also known as "long COVID" and includes symptoms such as fatigue, joint pain, muscle pain, et cetera. The COVID-19 virus may trigger hyper-inflammation associated with cytokine levels in the body.

Diabetes is a chronic metabolic disease characterized by improperly regulating proteins, carbohydrates, and lipids due to insulin deficiency or resistance. The increasing prevalence of diabetes poses a tremendous socioeconomic burden worldwide, resulting in the rise of many studies on Chinese herbal medicines to discover the most effective cure for diabetes. Sesame seeds are among these Chinese herbal medicines that were found to contain various pharmacological activities, including antioxidant and anti-inflammatory properties, lowering cholesterol, improving liver function, blood pressure and sugar lowering, regulating lipid synthesis, and anticancer activities.

  • The study investigates the first pass effect (FPE) in endovascular treatment (EVT) for medium vessel occlusion strokes, focusing on its predictors and impact on patient outcomes.
  • The analysis included 836 patients, revealing that FPE occurred in 36.1% and was linked to better functional outcomes as well as lower rates of mortality and intracranial hemorrhage.
  • FPE was significantly associated with favorable outcomes at 90 days, suggesting its importance in improving recovery and reducing complications in stroke patients.

Background: The incidence of stroke is increasing among younger people with human immunodeficiency virus (HIV). The burden of stroke has shifted toward the young people living with HIV, particularly in low- and middle-income countries. People infected with herpes zoster (HZ) were more likely to suffer stroke than the general population.

Background: The ChAdOx1 nCoV-19 vaccine is associated with vaccine-induced thrombosis and thrombocytopenia (VITT). Patients with end-stage renal disease (ESRD) under hemodialysis are at elevated risk of heparin-induced thrombocytopenia, which shares similar mechanisms with VITT. We aimed to examine the risk of VITT after the first dose of ChAdOx1 nCoV-19 vaccine using a self-controlled case series analysis (SCCS) in the hemodialyzed ESRD population.

Ji-Ming-Shan (JMS) is a traditional prescription use for patients with rheumatism, tendons swelling, athlete's foot, diuresis and even gout. This study developed a rapid and sensitive method for the analysis of JMS chemical components in the Traditional Chinese medicine (TCM) prescription and in the serum samples of rats which were administered with the herbal extract. Two mass spectrometric approaches were used namely Ultra-performance liquid chromatography-quadrupole time-of-flight-mass spectrometry (UPLC-Q-TOF-MS) method for the major metabolites of the JMS extract while Ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was employed for the detection of the JMS metabolites in the sera of rats.

Introduction: The neutrophil-to-lymphocyte ratio (NLR) may predict stroke-associated pneumonia, which is generally defined as pneumonia occurring in the first week after stroke. However, little is known whether the initial NLR is associated with pneumonia risk during the long-term follow-up in stroke survivors. We aimed to determine the relationship between admission NLR and the risk of post-stroke pneumonia within 1 year after discharge from acute stroke care.

Chronic kidney disease (CKD) is an independent risk factor for stroke and covert cerebrovascular disease, and up to 40% of stroke patients have concomitant CKD. However, the so-called "cerebrorenal interaction" attracted less attention compared to its cardiorenal counterpart. Diabetes is the leading cause of CKD.
